My .'said invention relates to improvei ments in stamping devices adapted for applying certain indiciatol lumber-,to indicate its grade and the. like as required by `certain lumberv organizations and consists 1n iinking the stamp yand forcing the 'same into the' grain orf the4 `material to beA marked. j
